In recent years business-to-business (B2B) e-commerce has been subject to major rethinking. A paradigm shift can be observed from document centric file-based interchange of business information to process-centric and, finally to service-based information exchange. On a business level, a lot of work has been done to capture business models and collaborative business processes of an enterprise; further initiatives address the identification of customer services and the formalization of business service level agreements (SLA). On a lower, i.e., technical level, the focus is on moving towards service-oriented architectures (SOA). These developments promise more flexibility, a market entry at lower costs and an easier IT-alignment to changing market conditions. This explains the overwhelming quantity of specifications and approaches targeting the area of B2B-these approaches are partly competing and overlapping. In this paper we provide a survey of the most promising approaches at both levels and classify them using the Open-edi reference model standardized by ISO. Whereas on the technical level, service-oriented architecture is becoming the predominant approach, on the business level the landscape is more heterogeneous. In this context, we propose-in line with the services science approach-to integrate business modeling with process modeling in order to make the transformation from business services to Web services more transparent.
